779599 - Consider doing animations of transforms on frames that are svg transformed off the main thread

Status: NEW

(Core :: Graphics, defect)

Comment 1

[David Zbarsky (:dzbarsky)]

Opacity already works.   Transform can't be animated until SVG attributes are promoted to properties.

Comment 2

[Emilio Cobos Álvarez (:emilio)]

I think this could work now? Do you know what's the issue if we just remove this?

Comment 3

[Robert Longson [:longsonr]]

What David said in comment 11 is still true i.e. we haven't unified transform attributes and transform properties. Having said that it might well work now anyway. I guess we'd have to try it and see.

Comment 4

[Emilio Cobos Álvarez (:emilio)]

Ah, I missed that transform wasn't mapped (I guess I confused it with transform-origin here).

So I guess we'd need to audit the transform syntax and make sure to use the CSS parser instead of this, or keep using the custom parser etc.

Comment 5

[Robert Longson [:longsonr]]

It needs custom parsing because transform attributes don't have units but CSS transform properties do.

Comment 6

[Emilio Cobos Álvarez (:emilio)]

Well sure but we already allow unitless lengths for all svg mapped attributes. But yeah cam mentioned the lack of commas in bug 878346 which might be more problematic.
